MARBLE is a STAMINA bus with the following parameters:
Parameter | Value |
---|
Address Channel | 32 bits |
Data Channel | 32 bits |
Response Channel | 1-bit merged with the data channel |
No. of Colours (=outstanding addresses) | 1 |
The MARBLE system used in AMULET3i is shown below. This figure illustrates the features listed above and shows how Harvard Architecture cores, (possibly with local RAM/ROM) can be supported under STAMINA.
